Neutral jwptaurus On May 15, 2012, jwptaurus from Delmar, DE wrote:

I dug up two of these from my mom's garden. One is about 2 feet tall. The tap root was about 10inches deep. Both plants quickly wilted before I could even get them home (a 25 minute drive). The big leaves have mostly wilted and died off, but after 4 days in the ground, there are new leaves developing all over it and the flowers continue to bloom. I have a relatively small flower bed, so i will dead head frequently as I don't want it to take over.

Our 'Zebrina' came up voluntarily a few years ago. I recently took pictures of it and posted to my facebook to see if anyone recognized it. A friend did and told me what it was. We love it! It is not invasive but it has spread a little this year. That's OK with me! I love the leaves and the flowers! Does anyone know if this has the medicinal purposes as other mallow plants?

I don't want to scare you off of this very pretty plant, but unless you want hundreds of seedlings all over the place, through the grass, growing in driveway cracks and even eavestroughs, you MUST not allow it to go to seed. This plant even competes with that horrible invasive Garlic Mustard that my house's previous owner let run rampant. On a positive note, this is a very pretty cut flower and looks nice with Veronica spicata and Cosmos. Plant with care.

This is to confirm the statement made by Terry. It's indeed a biennual. I sowed the seeds last year. I just now enjoying its flower. Currently I've only two in the perennial garden, will report of its offsprings' performance on following years for the record.

I have had this plant in my garden for several years now. I deadhead it daily until late in the season. This way it does not become invasive. I get a lot of comments on how beautiful they are.

Neutral Gabrielle On Jan 15, 2006, Gabrielle from (Zone 5a) wrote:

A pretty flower, but it LOVES to self-seed. I have it coming up everywhere. It has a long tap-root that makes it hard to pull up without landing on your bottom if it gives! My information says hardy in zones 3-10. Another name is Zebra Hollyhock.

Positive Marlina On Sep 4, 2005, Marlina from Blaine, MN (Zone 4b) wrote:

Don't think this plant makes it through our winter because it reappears in other places so believe it is a strong reseeder. Pretty plant I have had it in almost every light hear but deep shade..Does very well once it blooms keeps going until frost.

I found one of these growing as a 'weed' in the cracks of my patio and transplanted it into a garden bed in part sun. Now it has grown to full height and splendour, and looks wonderful amongst Bluebeard (Caryopteris), yellow yarrows, helianthus, and my Blue Satin Hibiscus.

does extremely well in zone 8, I have extra seed and they always reseed .

Neutral lmelling On Oct 27, 2004, lmelling from Ithaca, NY (Zone 5b) wrote:

Beautiful plant but doesn't do well in my yard (too moist). I planted this first in a "dry / average" year and it bloomed wonderfully but did not reseed. The next year I purchased another couple of them and it turned out to be a wet year. I have clay soil that tends to hold the moisture - this time they got very leggy and did not bloom well, only a couple at a time.

I've decided that while very pretty, they aren't worth the bother to purchase every year, because we never know whether it will be a wet or average season. The last few years it's tended on the wet side.

Very showy, tough plant with a profusion of pink/purple flowers. Flowers: June on. Best on poor, well-drained soils in full sun or partial shade. This plant bloomed the second year I had it and was spectacular.

I PURCHASED ONE PLANT AND NOW HAVE HUNDREDS. IT HAS SPREAD THROUGH MY WHOLE GARDEN. LOVE THE FLOWER. HAVE DUG UP YOUNG PLANTS AND GIVEN TO FRIENDS. TRANSPLANT VERY WELL. WILL BLOOM UNTIL FROST, VERY EASY TO GROW.

Will not overwinter in my garden (Zone 4A) reliably but generally returns from seed if I am lazy about dead-heading.
Very long bloom period, and some lovely cultivars make it worth keeping at least a few plants going.

I have this plant with flowers that are lavender streaked. After the first round of long lasting spring blooms faded, I trimmed them off and now have even more blooms in the stiff heat of a Mississippi July. I have this growing on the edge of an old arbor covered with wisteria that never blooms. Thank goodness for this little plant and the color it provides.

Positive Crimson On Sep 1, 2002, Crimson from Clarksville, TN (Zone 6b) wrote:

I LOVE these! It bloomed until frost killed it, long after all other things had been killed by frost. Needs staking, non-stop flowers.... difficult to impossible to move, long tap root. Blooms the first year. Cut down the stems in the autumn.

Neutral Terry On Jun 14, 2001, Terry from Murfreesboro, TN (Zone 7a) wrote:

French hollyhocks are generally grown as biennials or short-lived perennials. The standard flower color is white with purple veining, although lavender tinged flowers are also common among some of the varieties. They are shorter and stockier than their Hollyhock cousins, but they may still require staking to prevent them from flopping over.
